What can low airflow through an EVAP coil result in?

Low airflow through an evaporator coil can cause the coil to freeze. This occurs because the evaporator coil relies on a specific amount of airflow to function properly. When airflow is decreased, the refrigerant within the coil may not get adequately warmed by the passing air, leading to a situation where the temperature of the coil drops significantly. Moisture in the air can then condense on the coil and freeze, creating ice build-up. This ice not only limits heat exchange efficiency but can also lead to further complications and damage to the system if not addressed.

Thus, the consequence of low airflow is directly linked to the formation of ice on the coil, showcasing the importance of maintaining proper airflow for effective operation of air conditioning systems.
